Re: Two sine waves 180 degrees out of phase
But it isn't a duopoly. It's a monopoly, since Intel has all the power and AMD is more or less in the noise. As the article says, it is not feasible that AMD could get even 5% of market share in any really foreseeable timeframe.
Monopolies maintain their power through barriers to entry, and in Intel's case there are many of these none of which can go away at all quickly.
